Low Resistance and Audible Continuity Tests
WARNING
Do not run this test unless ACV = 0. Do not use this mode to check diodes.
1. Set the Rotary switch to the 200
Ω
position.
2. Connect the red test lead to the HI input terminal; black lead to the COM terminal.
3. Connect the tips of the test leads to both ends of the circuit under test.
4. Press the red TEST button and read the resistance on the LCD.
5. When the resistance of a circuit is less than approx. 100
Ω
the audible tone will sound.
AC Voltage Tests
1. Set the Rotary switch to the red 600V position.
2. Connect the red test lead to the HI terminal and the black test lead to the COM
terminal.
3. Connect the other end of the test leads to the circuit under test.
4. Read the voltage value on the LCD.
Data Hold Function
The Data Hold function freezes the displayed reading. Move the HOLD switch to the
rightmost position to freeze the displayed reading. The ‘H’ will appear on left side of the
display when the meter is in the Data Hold mode. Move the switch to the left position to
exit the Data Hold mode (the ‘H’ indicator will switch off).

Turn the meter is off and remove the test leads
2.
Remove the Phillips head screw on the rear of the meter
3.
